AppTaskExecutor<TConfig extends AppTask> class

Executes an AppTask.

This executor works closely with the singleton AppTaskController. Whenever an AppTaskExecutor is started (e.g. in a PeriodicTrigger), this executor is wrapped in a UserTask and put on a queue in the AppTaskController.

Later, the app (user) can start, cancel, or finalize a UserTask by calling the onStart(), onCancel(), and onDone() methods, respectively.

Special-purpose UserTasks can be created by an UserTaskFactory and such factories can be registered in the AppTaskController using the registerUserTaskFactory method.
